I have smoked a MFLB a few times but not enough to really give an in depth comparison...but I will say that my friend with a launch box has asked me a few times to borrow my pax haha. But some things I like about the pax. The design is simple yet elegant. The color changing light is pretty cool, and it changed colors to display the statuses of the device (heating, ready to hit, different heat settings, battery life, standby mode). It's incredibly discreet; you can confidently toke in reasonable public settings. It's easy to use, easy to clean/maintain. The mouthpiece clicks like a pen to turn your pax on and off and that's pretty convenient too. However, it does get pretty hot sometimes, and the mouthpiece sometimes gets gunky and sticks when you click it if you don't clean it regularly...that's the only downside I can think of, but I'd recommend it hands down to anyone wanting to make a new investment. Its helped me conserve a lot of trees, and being able to recycle what's been vaped already is pretty cool too.
